Introduce Your Students to Electrocardiography with a Free Experiment

Want a preview of one of our favorite human physiology experiments? Download “Intro to Electrocardiography” and teach students how to recognize the different wave forms seen in an EKG and associate these wave forms with activity of the heart.

for Teaching How the Body Works

Go Direct EKG Sensor

Measure Electrical Signals Produced During Heart or Muscle Contractions

The Go Direct EKG Sensor measures electrical activity in the heart and electrical signals produced during muscle contractions. The wireless options minimize the concern of cables getting caught and tangled during experiments. This sensor provides two separate outputs: one optimized for standard 3-lead EKG tracings and one optimized for surface EMG recordings. EMG recordings can also be rectified automatically by the sensor.

GDX-EKG $175

Hands-on learning opportunities include

• Compare and measure students’ electrocardiogram (EKG/ECG) waveforms.
• Determine heart rate by examining the number of QRS waveforms in a series of electrocardiograms.
• Study contractions of muscles (EMG) in the arm, leg, or jaw.
• Correlate measurements of grip strength and electrical activity with muscle fatigue.

Go Direct Blood Pressure Sensor

Easily Measure Human Blood Pressure

Hands-on learning opportunities include

• Measure and compare blood pressure and heart rate.
• Measure how exercise changes blood pressure.
• Observe how the “fight or flight” response changes blood pressure.

Go Direct Hand Dynamometer

Measure Grip and Pinch Strength and Perform Muscle Fatigue Studies 

The Go Direct Hand Dynamometer can be used to measure grip and pinch strength and to perform muscle fatigue studies. This sensor directly connects via Bluetooth® wireless technology or USB to student devices. Students can correlate muscle strength and fatigue when they pair the Go Direct Hand Dynamometer with the Go Direct EKG Sensor.

GDX-HD $135

Hands-on learning opportunities include

• Evaluate grip strength and different limb positions.
• Observe the effect of a conscious effort to overcome fatigue on hand grip strength.
• Compare the pinch strength of each finger.

Go Direct Respiration Belt

Measure Human Respiration Rate 

Hands-on learning opportunities include

• Observe how respiration rate changes after exercise or breath holding.
• Observe how respiration effort (the force exerted by the chest during respiration) changes after exercise or breath holding.
• Measure steps and step rate during a study with the built-in pedometer.
